Cases of MERS (Middle East Respiratory Syndrome) have been identified in multiple countries in the Arabian Peninsula.* There have also been cases in several other countries in travelers who have been to the Arabian Peninsula and, in some instances, their close contacts. Two cases were confirmed in May 2014 among two health care workers living in Saudi Arabia who were visiting the United States. For more information, see CDC’s MERS website.

CDC does not recommend that travelers change their plans because of MERS. Most instances of person-to-person spread have occurred in health care workers and other close contacts (such as family members and caregivers) of people sick with MERS. If you are concerned about MERS, you should discuss your travel plans with your doctor.

What is MERS?

MERS is a viral respiratory illness first reported in Saudi Arabia in 2012. It is caused by a virus that is different from any other virus that has been previously found in people. Symptoms of MERS include fever, cough, and shortness of breath. CDC is working with the World Health Organization and other partners to understand the public health risks from this virus.

What can travelers do to prevent MERS?

All travelers

All travelers can take these everyday actions to help prevent the spread of germs and protect against colds, flu, and other illnesses:

Health care workers

Exposure to camels

The MERS virus has been found in some camels, and some MERS patients have reported contact with camels. However, we do not know exactly how people become infected with the virus—many people with MERS have had close contact with a person sick with MERS.

The World Health Organization has posted a general precaution for anyone visiting farms, markets, barns, or other places where animals are present. Travelers should practice general hygiene measures, including regular handwashing before and after touching animals, and avoid contact with sick animals. Travelers should also avoid consumption of raw or undercooked animal products. For more information, see http://www.who.int/csr/disease/coronavirus_infections/faq/en/.

The World Health Organization considers certain groups to be at high risk for severe MERS; these groups include people with diabetes, kidney failure, or chronic lung disease and people who have weakened immune systems. The World Health Organization recommends that these groups take additional precautions:

If you are sick:

Cover your mouth with a tissue when you cough or sneeze, and throw the tissue in the trash.

Avoid contact with other people to keep from infecting them. This might mean delaying your travel until you are well.

Call a doctor if you develop a fever and symptoms of lower respiratory illness, such as cough or shortness of breath, within 14 days after traveling from countries in or near the Arabian Peninsula.* You should tell the doctor about your recent travel before you go in for an appointment.

Tell people who have been in close contact with you to monitor their health for 14 days after the last time they were around you.

They should call a doctor and tell them about your illness and travel history and their current symptoms.

If you get sick while you are traveling, see Getting Health Care Abroad for information about how to locate medical services overseas.

Clinician Information:

Health care providers should be alert to patients who develop fever and symptoms of respiratory illness within 14 days after traveling from countries in the Arabian Peninsula* or neighboring countries, excluding those who transited at airports without entering the countries.

Take precautions to reduce contact between any patient seeking care for symptoms consistent with MERS-CoV infection and other patients and staff. For more information, see CDC’s MERS Information for Health Care Providers.

Consider other more common causes of respiratory illness, such as influenza.
